IPC: G11B21/12
Filed: 1986-04-15
Abstract: PURPOSE:To prevent the wear of an effective cylinder and the data destruction in the effective cylinder by moving a head at a position at the outside of the effective cylinder while a disk device is not used for a series data access. CONSTITUTION:When the time of a timer 331 is over, since it is the time when a CPU 1 does not use the disk device for the purpose of data read/write, a timeout signal TO of the timer 331 energizes a set switch circuit 332 and new seek is generated automatically depending on the set content of the set switch circuit 332. The set content is a cylinder number at the outside of the effective cylinder. Thus, even when the CPU 1 gives no intervention, the head is in standby at the cylinder at the outside of the effective cylinder. Thus, the data destruction within the effective cylinder is prevented and the wear of the effective cylinder is avoided.

Filed: 1983-05-18
Abstract: PURPOSE:To enable to control an idling rotation number promptly by learning a feed-back correction volume and setting a learning correction volume for correcting a basic control value and taking a correlation with a target rotation number. CONSTITUTION:An idling control valve is provided in an auxiliary air passage bypassing a throttle valve of an internal-combustion engine. A correcting means of a learning correction volume takes a weighing average of a feed-back correction volume and a learning correction volume to renew the data of the same rotating number in RAM for using it as its new learning correction volume. A control value computing means computes a control value of a duty ratio by adding the feed-back correction volume and the learning correction volume to a basic control value. Proportional and integral constant correcting means change proportional and integral constants of the feed-back correction volume setting means. In this way, a correlation with a target rotating number is taken, so that a prompt control of an idling rotation number is possible as well as to improve the stability of the idling rotation
